Terror Danjah is a grime pioneer, with releases on Hyperdub and his own Harddrive Records. And he's teamed up with Four Tet for a new 12", "Killer/Nasty," with both songs streaming below. Four Tet's Kieran Hebden seems to take the lead on "Killer," a shuffling track dotted with selector shout-outs and elastic synths. "Nasty" lives up to its name - contorted, monstrous tears of distorted sub-bass congest the airborn vocals, but are deflected like tar against distilled water. Tet says you can buy it "late this week or early next week."
